Good afternoon.

This is the first time I am using the Siemens forum.

I have some questions and I need help.

I would like to limit the values entered by the user in the Logo Viewer.

In other words, the user only has the option to put a value from 0 to 350 for example. Currently I can not do this control. The user entered the full value of the variable from -20000 to +20000.

Is it possible to limit this range?

If yes, could someone tell me how, and / or send an example.

Another doubt. I would be able to block all LOGO screens, leaving only those created by me on the project. Remove screens from IO, Setup, Network, Data, etc .... Leave only the screens that run in the program. Is there such a possibility?

If yes, could someone tell me how, and / or send an example.

I await a return and thanks for the attention.

Thank you very much!

1.) Here is a possible solution, see attachment.
The entered value is checked to see if it is in the range of 0 to 350.
If this is the case, the entered value is passed on.
If this is not the case, the value 0 is passed on.

2.) You can not block this menue screens.
Changing the mode from Administrator to Operator disables some menu items in the system menu.
However, this requires the entry of a password, in the delivery state the password is LOGO.
When you return to the administrator mode, the menu items will be reactivated.
